tation-destroyer in Which an arrangement of gasolene tanks and burnerscombined with a suitable motor and other appurtenances are carried by aframe or vehicle mounted on AWheels and propelled along a railroad trackfor burning the Weeds along and on each side of the saine, and is in thenature of an iniprovement on the ,United States Letters atent ranted tolVilliam R. McKeen, Jr., and Art ur H. Fetters, January 23, 1906, Number810,793, for improvement in vegetau tion-destroyers.

Our invention has for its object to increase the intensity andefliciency of the burner flame and utilize the heat therefrom forvaporizing t e gasolene in its passage to the burners.

The invention consists in features of, novelty as hereinafter describedand claimed, reference being had to the accompanying drawing formingpart of this specification, whereon,

Figure l, is a top lan View` of a series of gasolene burners with) ordeiiector and vaporizing pipes (indicated by dotted lines) 'constructedand arranged according to our invention, Fig. 2, a side elevationthereof; Fig. 3, a vertical cross section to' enlarged scale through'one of the v burners and combined parts, on line 3, 3, in

Fig. l and Fig. 4, a top plan view thereof, broken away.

Like letters an'd numerals of reference denote like parts in all thefigures. n

a represents an end portion of the frame or vehicle, and b thecorresponding wheels of a vegetation-destroyer o the characterdescribed,in which the gasolene tank or reservoir, motor, and othernecessary equipment (not shown), being of the usual construction andconstituting no art of our present invention needs no furt erdescription.

Extending horizontally beyond the end portion a of the frame or vehicle(hereinafter referred to as the frame), over and between their combinedcasing the rails of the track c at a suitable'distance therefrom, is apreferably, shallow rectang lar casing or deiiector d Which is ad'ustaly secured` to the end of the frame c by rackets or hangers c fixed attheir loWer ends to the top of the casing d, preferabl by rivetsl,

ieo

and at their u per ends to t e end of the frame a by bo ts 2*, vtheholes for the latter through the end member of the frame a and thebrackets e respectively, being at equal distances apart so that onremoving the bolts 2, the casin d can be raised or lowered,

and refixed by t e bolts 2, at varying dis# tances fromthe track c asdesired.

To eachA side of the casing d is hin ed a similar casing or deector dwhich is a justable to a suitable distance from the surface of theground adjacent to the corresponding side of the track c, the casings dand d being preferably open at the bottom, but otherwise closed on allsides, except at the top, through which are'formed preferably, circularopen 1 ings3 at a suitable distance aparts Through each o ening-S 1sremovably 1nserted a correspon ingly shaped burner tube l (see Figs. 8and 4) Whichdepends for aI suitable distance Within the casing d (d) andis preferablyformed at its upper end with an outer surrounding flange or11p 4 which bears'.

on the top of the casin d (ol and makes an air-tightl joint therewit vWithin Leach casing d, d', is arranged, a pipe 5 (or series thereofcommunicating with each otherl'which ispreferably, bent or otherwisedirected to and fro, around and adjacent to, but clear of, the

burner tubes 4 as shown, and held and tightened against the inside ofthe top of the casing d (d) by clamps or staples 6, the

prongs of Which pass through, and are' clenched against the outside ofthe top of, the casing d (d) by nuts 6. Or the pipe 5 'may be otherwisearrangediand secured at a suitable level V'Within vthe casing d (df) -inany other desired manner. Or in lieu of a pipe 5, any other form ofreceptacle or cham er se-- cured to, or integral with the walls of thel.casings (1,11 maybe used as the equivalent thereof.

The pipe'5 of each casing d, d', communie cates at one end With agasolene tank or res- ;ervoir (not shown) carried on the frame a asbefore mentioned, by a pipe 5', between which' andthe pipe 5 is 'anuniversal 'oint 7 allow for the said adjustments of t e cas ings d, d',while the other end of each pipe 5 r communicates by ine'ans'of asuitable elbow 3 l "with a series of pipes 9 fuel means for the saidfuel from a suitable which are arranged over and adjacent to the top ofeach casing d,d,asshown.l

Projecting. from and communicating With the pipes 9 on their undersidelimmediately over each burner tube 4, is a nipple l() (see Figs. 3 and 4)the 'passageeway Ythrough which from the. interiorof the pipes 9 to itsoutlet into the upper is packed' with fine wire netting". or othersuitable permeable material ll adapted to filter the gasolene vapor inpassing therethrough as lhereinafter referred to.

nY the operation of our paratus as above described, other liquid fuel)being admit Y tank` or. reservoir on-the frame a through the 'pipes v5into the pipes 5 i ings d, d', heat from anyI available source isinitially applied to the pipes 5V and thereby vaporin'es orconverts the.gasolene therein into gas whichpasses from the pipesthrough the gaspipes9, and thence gas'olene (or ples 10 (wherein it is straine il) intothe burner tubes, 4, and in so', loing air is 'drawn by the inducedcurrent from' the spacesbetweeii the tubes ALan'd' nipples 10, and.mixing with the gas passes therewith through the burner tubes 4, at thelower ends of which, or thereaboutfwithin the casings d,

d, the resulting mixture is ignited .and 'an intense heat-therebygenerated, 'which' being deflected' downward bythe top of the cas'- ingsd, d', is concentrated upon and destroys the'vegetatxion beneath as thetrack, and. at the same time maintains the constant vaporization of the.gasolcne within the pipes-5 durnig the' operation.

y By this invention` the flame from the.

burners is intensified and bclngconfined vwithin the casings ordciiectors d, d', and utilized for vaporizing-the gasolene instead ofbeing dispersed or dissipated into the surrounding atmosphere, itselliciencv is greatly increased; moreover, the vegetation is destroyed.more] thoroughly and uniformly, with less risk apparatus on thefraineorvchicle.
